I usually don't do reviews. Don't know what to say. My story on this bender1st-this is a tube bender, measuring the OD(outside diameter) of aluminum tube. This is what I have and needed. Pipe is measured by ID( inside diameter)So, make sure you know what you have,tube/pipe from the startB-I have a shop, brand new, so no place to mount the base yet-so I skinned a tree just a little and mounted the base on it. Very happy I thought of that, thought outside the box per say3-since I had never done this before and only one aluminum tube so no room for error. I marked the center of the tube w marker, placed it in center of jig, rolled it towards the hold clamp and marked it there. Then placed it in hold clamp and started bending. It ended up being almost perfect. Luck/Skill=you decide. Placed a 2'x3' carpenter square on it marked the long side and cut off 1/4"D-this was exactly what I needed and affordable for me. I'm a DisVet so not a lot of money to waste or throw awayFifth-this works great, all manual, but I have more strength so for it is PERFECT and preciseInfinity/Last/Z-it is still mounter on tree(2 weeks now approx) still bending tube, for friends now, making boat hold on brackets and 4"tall rails around top of Jon boats
